Bella your paragraph is so good I agree I would also pick Mario, I also have some things to add onto it.
If I could be friends with one person in this story it would be Mario. I would be friends with Mario because he is lonely and doesn’t have a lot of friends.I think that he doesn’t have a lot of friends is because usually on Saturday and Sunday you would be with your friends, not selling papers at the subway. Also because he seems nice, kind and caring, the reason that I think that he is nice, kind and caring is because he wanted to keep a cricket that he found at the subway and begged to keep it. That is why I would be friends with Mario.
